Abstract
This invention relates to wax formulations comprised of specific poly(oxyalkylenated) colorants having alkenyl succinic anhydride (ASA) terminal groups. Preferably the wax formulation is a crayon. Such polymeric ASA-capped colorants provide excellent coloring, decreased migratory properties, and improved balanced burning characteristics over traditional crayon colorants, pigments, and dyestuffs. This invention also concerns methods of making the aforementioned colored crayon formulations as well as other colored wax articles, such as candles.
